An epidemic is when a disease breaks out in one specific area, but a pandemic is when it spreads over a large region, such as a whole country, continent or the world. The prefixes come from Greek: Epi = on, at, upon Pan = all It's do with location rather than number of cases. For example, 10,000 cases in one city would be an epidemic, but 10,000 cases across the would would be a pandemic.

Here's Miss Lien's answer as an answer. So you can mark it resolved. An epidemic is when there are many people suffering from the same decease. I don't know the exact amounts, but a lot. A pandemic is when the epidemic is spread out worldwide. Like now with the Covid-19, this is really a pandemic.

I got the point. Thanks a lot.
